Regulated M1 mRNA splicing in influenza virus-infected cells.
Influenza virus RNA segment 7 generates three poly(A)+ RNAs, M1 mRNA, M2 mRNA and mRNA3, the last of which has almost no coding capacity; M2 mRNA and mRNA3 derive from M1 mRNA by removal of a single intron. The kinetics of M1 and M2 mRNA accumulation in the cytoplasm of productively infected cells were studied by means of a quantitative RNA protection assay; the ratio of M2 mRNA to M1 mRNA incr...
متن کاملMutations of Pre-mRNA Splicing Regulatory Elements: Are Predictions Moving Forward to Clinical Diagnostics?
For more than three decades, researchers have known that consensus splice sites alone are not sufficient regulatory elements to provide complex splicing regulation. Other regulators, so-called splicing regulatory elements (SREs) are needed. Most importantly, their sequence variants often underlie the development of various human disorders. However, due to their variable location and high degene...
متن کاملTRAP150 activates pre-mRNA splicing and promotes nuclear mRNA degradation
TRAP150 has been identified as a subunit of the transcription regulatory complex TRAP/Mediator, and also a component of the spliceosome. The exact function of TRAP150, however, remains unclear. We recently identified TRAP150 by its association with the mRNA export factor TAP. TRAP150 contains an arginine/serine-rich domain and has sequence similarity with the cell death-promoting transcriptiona...
متن کاملLinks between mRNA splicing, mRNA quality control, and intellectual disability.
In recent years, the impairment of RNA binding proteins that play key roles in the post-transcriptional regulation of gene expression has been linked to numerous neurological diseases. These RNA binding proteins perform critical mRNA processing steps in the nucleus, including splicing, polyadenylation, and export. In many cases, these RNA binding proteins are ubiquitously expressed raising key ...
متن کاملRNAcatalyses nuclear pre-mRNA splicing
In nuclear pre-messenger RNA splicing, introns are excised by the spliceosome, a dynamic machine composed of both proteins and small nuclear RNAs (snRNAs). Over thirty years ago, after the discovery of self-splicing group II intron RNAs, the snRNAswere proposed to catalyse splicing. However, no definitive evidence for a role of either RNAor protein in catalysis by the spliceosome has been repor...
